From: "Peter E. Berger" <pber...@brimson.com>
The io_ti driver fails to download firmware to Edgeport
devices such as the EP/416, even when the on-disk firmware image
(/lib/firmware/edgeport/down3.bin) is more current than the version on
the EP/416. This patch adds a "fw_version" field to edgeport_serial,
which allows download_fw() to indicate when a newer on-device firmware
version is being retained.
